#8 I assumed the squeaking was coming from the girlfriend, probably trying to be quiet (heard from a distance). But I guess a regular squeak from the bed could sound like a guinea pig running on its wheel. :)

58, Guinea pigs should not run on wheels, it will damage their spine because they are not meant to bend backwards like that. I think OP means the noise guinea pigs make, called wheeking. It is rather cute when you hear it! :)

Well, it's not like he can kick his girlfriends ass. The worst he could do is reveal it to people and let the slut-shaming commence (but I doubt that would phase her).
Regardless, his brother deserves something less than kind to come his way. His brother went along with it for three months, never once hinting at the fact OP's girlfriend is terrible.
Hopefully karma gets them both back.

actually I believe it us justified to beat up the male in this scenario being it is his BROTHER. siblings hurt each other over less. I also think, though its my opinion, that his own brother did that to him is worse than her just cheating.

His brother is his flesh and blood, they grew up together, they're supposed to love each other. Girlfriends are not as permanent. So yeah, it's the brother that his the true betrayal and his ass OP should be kicking.

A male is physically stronger than a female. A man should never hit a woman. EVER!! There's no valid justification that can be given. If OP has a sister, let her loose on the skank. Or tell your mum what the ex did. She can kick your brothers ass and beat the shit out of the bitch, it's an even match then. Plus, mums have a "special" way of dealing with things.

If a girl has the balls to put her hands on a guy, something has to be said about her mental state at the time. No woman in her sane mind would put up fisticuffs against a guy. A real man would restrain her in a bear hug or something to that effect, or simply walk away. The only time I ever raised my fist to a guy was after he punched me in the face, fracturing my eye socket and cheek bone. That was an extreme situation where I felt I was going to be beaten to death. We can be conniving, vicious and mental but we never deserve to be hit.

@145 To say you would prefer one form of abuse over another is repugnant. One goes hand in hand with the other and where there is one form at the start, the other eventually occurs and a cycle is formed. If you wish to discuss abuse, mental or physical, pm me as I don't wish to be a hijacker.

#143 "we never deserve to be hit". First, you can't decide what you deserve by yourself. Other people decide it, if you involve them in something.
Also, this sentence sounds like you're giving yourself a free pass for any kind of abuse towards a man without physical consequences."a male is physically stronger than a female" well if you want to go all the way down the stereotype road, I'll say that women are way better at verbal and emotional abuse than men, and therefore should never use it on men. No double standard. Both fighting method are equally violent, not in the same way. I'm a man, verbally and emotionally bullied by most people I knew in junior high, and I wish I got beaten up instead, because it hasn't as much long-term consequences, and the non-physical forms of abuse were so insidious that I couldn't even explain what happened exactly. Personnally, I am physically weaker than a lot of women, so a bear hug is usually out of question. If a woman goes apeshit on me, the simplest solution I have is a quick punch to the breastbone. Not that harmful and forces you to stop right away.
Now in this case, physical violence isn't justified against the girl because shaming her in front of everyone OP knows is much more efficient.

I see that my comment regarding my disapproving view on hitting women is being down voted...
Let me just clarify that I'm not defending OP's bitch ex, I just know how devastating an abusive relationship can be and I honestly don't believe that anyone deserves to be trapped inside one.

Can also be the sound of denial he is hearing. I don't know a human being that could mistake it for an entire 3 months without investigating the noise once or twice. Sounds like a real life Dale Gribble kind of thing...

And why does #42 get thumbed up and I get thumbed down? That was exactly what I meant in my comment as well! Sex bed squeaks are way too rhythmic to sound like a little animal making some noises. There's no way he didn't catch on after a few minutes let alone a few months.
